NGC 6554. During the plate scanning for ESGC, I noted this as "20-30 stars in a 20 arcmin area." I don't believe that these stars are a real cluster, but they do stand out from the field enough that they could be picked up during a visual sweep. JH's comment "Has several double stars in it" also makes it clear that he was seeing the same concentration of stars. I put the center somewhat east-northeast of JH's position, but the identity is not in question.
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL S.
Steve Coe, observing with a 13" f/5.6, notes: "No definate cluster at 100X. This object is marked as nonexistant and it may be the truth."
